Nexa miners (NexaPow)
ASIC miners for Nexa (NEXA), NexaPow algorithm – for example the DragonBall A21. For every machine you can see its hashrate and power draw.
Nexa is a network derived from Bitcoin Cash, focused on scalability and tokens. We do not have live returns data for Nexa yet – we will calculate a machine's returns on request based on the current state of the network.

Profit = today’s revenue based on network difficulty and the exchange rate − electricity at the selected price. Our hosting = the cheapest location with free capacity (Nigeria #2), price converted from USD at today’s exchange rate. Revenue changes; this is not a forecast.
How to choose a Nexa miner
First decide where the machine will run – that determines the cooling. For each type we show the machines from this collection that earn the most today from 1 kWh of electricity.
-
hosting, workshop
Air-cooled
The most common and cheapest option: fans cool the machine, so it only needs a supply of cool air and a way to remove the heat. It is loud, though (usually 70–80 dB), so it does not belong in a flat – it suits our hosting, a workshop or a plant room, and at home only with a soundproof box.

How hosting works -
quieter, heat for heating
Hydro (water cooling)
A liquid in a closed loop cools the chips and a dry cooler or heat exchanger removes the heat. Hydro machines are quieter and more powerful, but they need a water loop and usually a three-phase supply. You can use the heat to warm water or for heating.
There are none in this collection right now. Write to us – we will check availability.
Water loops for Hydro -
farms, almost silent
Immersion cooling
The machine is submerged in dielectric fluid in an immersion tank – it is almost silent and the chips stay at an even temperature. It needs a tank, a pump and a cooler, so it is best suited to farms and hosting.

Nexa miner comparison
Sorted from the most efficient – fewest joules per unit of hashrate. We recalculate revenue every hour, and profit using the electricity price selected above the miners: on hosting at 1.14 Kč/kWh.
| Model | Hashrate | Power | Efficiency | Cooling | Noise | Price from | Revenue / day | Profit / day |
|---|---|---|---|---|---|---|---|---|
| DragonBall A21 | 3.4 GH/s | 1,800 W | 529 J/GH | Air | 75 dB | from 96 815 Kč | – | on request |
Hashrate, power draw and noise are stated by the manufacturers. Efficiency = power draw ÷ hashrate. Revenue = hashrate × today’s revenue of the algorithm’s most profitable coin (before electricity and pool fees); profit = revenue − electricity at the selected price. For machines with several hashrate options we use the base hashrate from the product card.
At home or on our hosting?
The result of mining depends mainly on the electricity price. Comparison for the machines in this collection.
At home or at your business
- Grid electricity costs a Czech household roughly 4.5–6.5 Kč/kWh (2026); it is cheaper from your own solar panels or on a business tariff.
- A powerful ASIC needs its own circuit and ventilation, and you have to expect noise – air-cooled machines are usually 70–80 dB.
- You can use the miner’s heat for heating, but in summer you have to get rid of it.
On our hosting
- Electricity from 1.14 Kč/kWh including management (Nigeria #2), 7 locations with free capacity.
- With prepaid electricity, up to 30% cheaper.
- New miners bought from us that run on our hosting come with a 7-year warranty. We take care of noise, cooling and repairs.
Profit = today’s revenue − electricity for 24 hours, before pool fees. Network difficulty and the exchange rate change; this is neither a forecast nor a promise of revenue.
FAQ about Nexa miners
What is Nexa and how is it mined?
Nexa (NEXA) is a proof-of-work network derived from Bitcoin Cash, focused on high throughput and native tokens. It is mined with the NexaPow algorithm on ASIC miners.
How much does a Nexa miner earn per day?
We do not yet have live network difficulty data for Nexa, so we do not show revenue on the cards. We will calculate it for you on request based on the current state of the network and your electricity price.
Can I place a Nexa miner in your hosting?
Yes, we place the machines in a data centre with cheaper electricity and take care of their operation. Prices by location are on the page Miner hosting.
